Strictly has been wiping the floor with X Factor in the ratings war every weekend, so head honcho Simon Cowell is pulling out the big guns for the series finale.

That’s right, he’s bringing in the heavies – and that can only mean one thing. One Direction.

Expect a massive spike in the ratings as the heart-throb boyband – who surprisingly came only third in the 2010 series – wrap up proceedings at the live final at Wembley Arena on December 15.

Si reckons the biggest group on the planet right now with their aggressively loyal fanbase will have audience figures soaring.

And of course he’s right.

While Directioners will be hoping for a medley from Harry Styles, 19, Louis Tomlinson, 21, Liam Payne, 20, Zayn Malik, 20 and Niall Horan, 19 – I’m told they will only have time to sing one hit song because of their tight schedule.

But it’ll be the SECOND time this series you’ll see them as they are set to perform later this month to celebrate the show’s 10 year anniversary.
